Influence of Enzyme Treatment on Wetability and Modulus of Elasticity of Poplar
A study of xylanase enzyme treatment on poplar specimens was conducted to improve specimens ’ surface wetability and modulus of elasticity.The results showed that enzyme concentration and treatment duration had noticeable effect on the surface energy of poplar samples.Generally,high enzyme concentration and long treatment increased the surface contact angle and free energy,but modulus of elasticity increased at the initial stage,and then decreased.It was found,in this study,that the optimized treatment time was 6 hours with an enzyme concentration of 1 mL/g.
